Abstract
In this workshop we will explore the opportunities unleashed by progress in muon-based experiments, with particular focus on a multi-TeV muon collider. We will discuss both Standard Model precision physics and the search for new phenomena at the highest possible accelerator energies.

Muon beams up to multi-TeV energies hold the potential to revolutionize the exploration of the high-energy frontier. At the same time, they require the development of new methods and tools in particle theory as well as in collider experiments and accelerator physics. Our workshop will bring together experts, as well as young generations, from these communities and will provide the setting to weave together the strategy to get to the next new kind of particle collider. In addition the workshop will serve as a platform to develop possible synergies with all the communities potentially interested in muon beams, and in the technologies that are necessary to develop it. Thus we will discuss the synergy from intense proton beams and the intense hadron and neutrino beams that they can source, enabling exploration of the lepton and neutrino sector, as well as dark matter and dark sectors and other investigations at the intensity frontier.

During the workshop we will organize several pedagogical activities aimed at increasing the awareness and competence in the high energy physics theoretical community on the exciting possibilities enabled by progress expected in muon beams and collider technologies. We will also organize small groups focused on further developing key tools needed for muon collider R&D.
